Error(SPMHDB-180): Design revision 23.1 is newer that current program version

Someone took a 17.4 database, saw the warning that any saves would upconvert the data to 23.1 and forgot.  Saved over the 17.4

Find someone with 23.1 installed and have them down-rev changes back to 17.4.  

There are minor padstack and design features added in 22 and 23 that will be dropped when down-reving to 17.4.

Hi Sir, 

Thanks much for your response. 

We have 23.1 version also. How to down rev? Could you please help with this?

With Orcad X 23.1, there's an >Export dialog towards the right, after >Manufacture.

>Export >More >Down Rev Design

I think it's in a different menu location(next to >File maybe) for Allegro 23.1 but right now one my engineers is using my Algx license.

Thanks much for your support.
